USB4 40Gbps NVMe enclosure

The Syba SY-TDB40178 is a USB4 40Gbps enclosure that accepts M.2 NVMe SSDs with B+M-Key connectors. It draws power from the host port and needs no external adapter. The aluminium case provides passive cooling for sustained workloads.

B+M-Key M.2 NVMe only

Only M.2 NVMe drives with B+M-Key or M-Key pinouts fit this enclosure; SATA-based M.2 modules are not supported. Compatible lengths include 2230, 2242, 2260, 2280 and 22110. The internal interface is PCIe NVMe exclusively.

Thunderbolt 3/4/5 host required

Full 40Gbps throughput requires a host port that implements Thunderbolt 3, 4 or 5 alongside USB4. The enclosure works with Windows, macOS, Linux, Unix, Android and iOS. It adds no active cooling, so system airflow must handle drive heat.

商品問答

What does the 40 Gbps figure mean for real-world file transfers?

The enclosure connects over USB4 or Thunderbolt 3/4/5 at up to 40 Gbps, so an NVMe drive inside can deliver its full sequential read and write speed instead of being limited by a slower port.

Which interface standard caps the speed and what does it allow?

USB4 Gen 4x4 and Thunderbolt 3/4/5 both cap at 40 Gbps, letting the M.2 NVMe B+M-Key SSD run at PCIe lane speed without a separate power adapter.

What physical M.2 sizes and keys fit inside the aluminium case?

The dock accepts M.2 NVMe drives with M-Key or B+M-Key connectors in 2230, 2242, 2260, 2280 and 22110 lengths; SATA or B-Key-only SSDs are not supported.
